| Abstract: | Based on the principles of electrical and mechanical dynamics,the dynamical equations of hybrid excitation synchronous machine(HESM) in the d-q coordinates rotating synchronously with the rotor are derived.The decoupling control and full linearization of HESM system are realized with nonlinear state feedback and coordinates transformation.The HESM is decomposed into three linear subsystems,d axis flux subsystem,q axis flux subsystem and rotation speed subsystem.Simulation results show that HESM control system based on the design of input and output decoupling and linearization achieves high dynamic performance. |
